      Pull clk updates from Stephen Boyd:
       "The large diff this time around is from the addition of a new clk
        driver for the TI Davinci family of SoCs. So far those clks have been
        supported with a custom implementation of the clk API in the arch port
        instead of in the CCF. With this driver merged we're one step closer
        to having a single clk API implementation.
      
        The other large diff is from the Amlogic clk driver that underwent
        some major surgery to use regmap. Beyond that, the biggest hitter is
        Samsung which needed some reworks to properly handle clk provider
        power domains and a bunch of PLL rate updates.
      
        The core framework was fairly quiet this round, just getting some
        cleanups and small fixes for some of the more esoteric features. And
        the usual set of driver non-critical fixes, cleanups, and minor
        additions are here as well.
      
        Core:
         - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
         - debugfs ops macroized to shave some lines of boilerplate code
         - Always calculate the phase instead of caching it in clk_get_phase()
         - More __must_check on bulk clk APIs
      
        New Drivers:
         - TI's Davinci family of SoCs
         - Intel's Stratix10 SoC
         - stm32mp157 SoC
         - Allwinner H6 CCU
         - Silicon Labs SI544 clock generator chip
         - Renesas R-Car M3-N and V3H SoCs
         - i.MX6SLL SoCs
      
        Removed Drivers:
         - ST-Ericsson AB8540/9540
      
        Updates:
         - Mediatek MT2701 and MT7622 audsys support and MT2712 updates
         - STM32F469 DSI and STM32F769 sdmmc2 support
         - GPIO clks can sleep now
         - Spreadtrum SC9860 RTC clks
         - Nvidia Tegra MBIST workarounds and various minor fixes
         - Rockchip phase handling fixes and a memory leak plugged
         - Renesas drivers switch to readl/writel from clk_readl/clk_writel
         - Renesas gained CPU (Z/Z2) and watchdog support
         - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support
         - Qualcomm PM8921 PMIC XO buffers
         - Amlogic migrates to regmap APIs
         - TI Keystone clk latching support
         - Allwinner H3 and H5 video clk fixes
         - Broadcom BCM2835 PLLs needed another bit to enable
         - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix
         - i.MX6UL/ULL epdc_podf support
         - Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC"

      arch/sh: pcie-sh7786: handle non-zero DMA offset · bf9c7e3d
      Thomas Petazzoni authored
      On SuperH, the base of the physical memory might be different from
      zero. In this case, PCI address zero will map to a non-zero physical
      address. In order to make sure that the DMA mapping API takes care of
      this DMA offset, we must fill in the dev->dma_pfn_offset field for PCI
      devices. This gets done in the pcibios_bus_add_device() hook, called
      for each new PCI device detected.
      
      The dma_pfn_offset global variable is re-calculated for every PCI
      controller available on the platform, but that's not an issue because
      its value will each time be exactly the same, as it only depends on
      the memory start address and memory size.

      arch/sh: pcie-sh7786: adjust the memory mapping · 79e1c5e7
      Thomas Petazzoni authored
      The code setting up the PCI -> SuperHighway mapping doesn't take into
      account the fact that the address stored in PCIELARx must be aligned
      with the size stored in PCIELAMRx.
      
      For example, when your physical memory starts at 0x0800_0000 (128 MB),
      a size of 64 MB or 128 MB is fine. However, if you have 256 MB of
      memory, it doesn't work because the base address is not aligned on the
      size.
      
      In such situation, we have to round down the base address to make sure
      it is aligned on the size of the area. For for a 0x0800_0000 base
      address with 256 MB of memory, we will round down to 0x0, and extend
      the size of the mapping to 512 MB.
      
      This allows the mapping to work on platforms that have 256 MB of
      RAM. The current setup would only work with 128 MB of RAM or less.

      arch/sh: pcie-sh7786: adjust PCI MEM and IO regions · 5da1bb96
      Thomas Petazzoni authored
      The current definition of the PCIe IO and MEM resources for SH7786
      doesn't match what the datasheet says. For example, for PCIe0
      0xfe100000 is advertised by the datasheet as a PCI IO region, while
      0xfd000000 is advertised as a PCI MEM region. The code currently
      inverts the two.
      
      The SH4A_PCIEPARL and SH4A_PCIEPTCTLR registers allow to define the
      base address and role of the different regions (including whether it's
      a MEM or IO region). However, practical experience on a SH7786 shows
      that if 0xfe100000 is used for LEL and 0xfd000000 for IO, a PCIe
      device using two MEM BARs cannot be accessed at all. Simply using
      0xfe100000 for IO and 0xfd000000 for MEM makes the PCIe device
      accessible.
      
      It is very likely that this was never seen because there are two other
      PCI MEM region listed in the resources. However, for different
      reasons, none of the two other MEM regions are usable on the specific
      SH7786 platform the problem was encountered. Therefore, the last MEM
      region at 0xfe100000 was used to place the BARs, making the device
      non-functional.
      
      This commit therefore adjusts those PCI MEM and IO resources
      definitions so that they match what the datasheet says. They have only
      been tested with PCIe 0.

      arch/sh: pcie-sh7786: exclude unusable PCI MEM areas · d62e9bf5
      Thomas Petazzoni authored
      Depending on the physical memory layout, some PCI MEM areas are not
      usable. According to the SH7786 datasheet, the PCI MEM area from
      1000_0000 to 13FF_FFFF is only usable if the physical memory layout
      (in MMSELR) is 1, 2, 5 or 6. In all other configurations, this PCI MEM
      area is not usable (because it overlaps with DRAM).
      
      Therefore, this commit adjusts the PCI SH7786 initialization to mark
      the relevant PCI resource as IORESOURCE_DISABLED if we can't use it.

      arch/sh: pcie-sh7786: mark unavailable PCI resource as disabled · 7dd7f698
      Thomas Petazzoni authored
      Some PCI MEM resources are marked as IORESOURCE_MEM_32BIT, which means
      they are only usable when the SH core runs in 32-bit mode. In 29-bit
      mode, such memory regions are not usable.
      
      The existing code for SH7786 properly skips such regions when
      configuring the PCIe controller registers. However, because such
      regions are still described in the resource array, the
      pcibios_scanbus() function in the SuperH pci.c will register them to
      the PCI core. Due to this, the PCI core will allocate MEM areas from
      this resource, and assign BARs pointing to this area, even though it's
      unusable.
      
      In order to prevent this from happening, we mark such regions as
      IORESOURCE_DISABLED, which tells the SuperH pci.c pcibios_scanbus()
      function to skip them.
      
      Note that we separate marking the region as disabled from skipping it,
      because other regions will be marked as disabled in follow-up patches.

      arch/sh: pci: don't use disabled resources · 3aeb93a0
      Thomas Petazzoni authored
      In pcibios_scanbus(), we provide to the PCI core the usable MEM and IO
      regions using pci_add_resource_offset(). We travel through all
      resources available in the "struct pci_channel".
      
      Also, in register_pci_controller(), we travel through all resources to
      request them, making sure they don't conflict with already requested
      resources.
      
      However, some resources may be disabled, in which case they should not
      be requested nor provided to the PCI core.
      
      In the current situation, none of the resources are disabled. However,
      follow-up patches in this series will make some resources disabled,
      making this preliminary change necessary.

      arch/sh: make the DMA mapping operations observe dev->dma_pfn_offset · ce883130
      Thomas Petazzoni authored
      Some devices may have a non-zero DMA offset, i.e an offset between the
      DMA address and the physical address. Such an offset can be encoded
      into the dma_pfn_offset field of "struct device", but the SuperH
      implementation of the DMA mapping API does not observe this
      information.
      
      This commit fixes that by ensuring the DMA address is properly
      calculated depending on this DMA offset.

      The SH7786 has different physical memory layout configurations,
      configurable through the MMSELR register. The configuration is
      typically defined by the bootloader, so Linux generally doesn't care.
      
      Except that depending on the configuration, some PCI MEM areas may or
      may not be available. This commit adds a helper function that allows
      to retrieve the current physical memory layout configuration. It will
      be used in a following patch to exclude unusable PCI MEM areas during
      the PCI initialization.

      drm/amd/display: Fix regamma not affecting full-intensity color values · b2f3f592
      Leo (Sunpeng) Li authored
      Hardware understands the regamma LUT as a piecewise linear function,
      with points spaced exponentially along the range. We previously
      programmed the LUT for range [2^-10, 2^0). This causes (normalized)
      color values of 1 (=2^0) to miss the programmed LUT, and fall onto the
      end region.
      
      For DCE, the end region is extrapolated using a single (base, slope)
      pair, using the max y-value from the last point in the curve as base.
      This presents a problem, since this value affects all three color
      channels. Scaling down the intensity of say - the blue regamma curve -
      will not affect it's end region. This is especially noticiable when
      using RedShift. It scales down the blue and green channels, but leaves
      full-intensity colors unshifted.
      
      Therefore, extend the range to cover [2^-10, 2^1) by programming another
      hardware segment, containing only one point. That way, we won't be
      hitting the end region.
      
      Note that things are a bit different for DCN, since the end region can
      be set per-channel.
