Merge tag 'v4.12-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next Pull rockchip clk driver updates from Heiko Stuebner: General rockchip clock changes for 4.12. Contains some new clock-ids as well as fixups of the clock-ids on rk3368 timers, which were unused and completely wrong (more and differently named timers). Also there is one new clock on rk3328 using the muxgrf type, a fix for pll enablement which should wait for the pll to lock before continuing, some more critical clocks and the rename of the rk1108 to rv1108, as the soc seems to have been using a preliminary name before its actual release. The plan is to have the driver changes (pinctrl, clk) go through the respective maintainer trees and once everything landed in mainline do the rename of the devicetree files. With the dts-include change in the clock rename, we also keep everything compiling and thus bisectability. * tag 'v4.12-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip: clk: rockchip: add pll_wait_lock for pll_enable clk: rockchip: rename RK1108 to RV1108 dt-bindings: rk1108-cru: rename RK1108 to RV1108 clk: rockchip: mark some rk3368 core-clks as critical clk: rockchip: export SCLK_TIMERXX id for timers on rk3368 clk: rockchip: describe clk_gmac using the new muxgrf type on rk3328 clk: rockchip: add clock ids for timer10-15 of RK3368 SoCs clk: rockchip: fix up rk3368 timer-ids clk: rockchip: add rk3328 clk_mac2io_ext ID clk: rockchip: Set "ignore unused" for PMU M0 clocks on rk3399

Starting with R-Car H3 ES2.0, the parent of RCLK is selected using MD28. Add support for that, but retain the old behavior for R-Car H3 ES1.x and M3-W ES1.0 using a quirk. Inspired by a patch by Takeshi Kihara in the BSP. Signed-off-by:

The Clock Pulse Generator / Module Standby and Software Reset module in R-Car H3 ES2.0 differs from ES1.x in the following areas: - More core clocks (S0D2, S0D3, S0D6, S0D8, S0D12), - Different parent clocks for AUDMAC, EtherAVB, FCP, FDP, IMR, SYS-DMAC, VIN, VSPB, VSPI, - Removal of modules CSI21, FCPCI, FCPF2, FCPVD3, FCPVI2, FDP1-2, USB3-IF1, VSPD3, VSPI2, - Addition of modules EHCI3, HS-USB-IF3, USB-DMAC3-0, USB-DMAC3-1. The goal is twofold: 1. Support both the ES1.x and ES2.0 SoC revisions in a single binary for now, 2. Make it clear which code supports ES1.x, so it can easily be identified and removed later, when production SoCs are deemed ubiquitous. This is achieved by: - Updating the clock tables for the latest revision (ES2.0), but not removing clocks that only exist on earlier revisions (ES1.x), - Detecting the SoC revision at runtime using the new soc_device_match() API, and fixing up the clocks tables to match the actual SoC revision, by: - NULLifying core and module clocks of modules that do not exist, - Reparenting module clocks that have a different parent on ES1.x. Based on R-Car Gen3 Hardware User's Manual rev. 0.53E. Signed-off-by:

The same SoC may have different clocks and/or module clock parents, depending on SoC revision. One option is to use different sets of clock tables for each SoC revision. However, if the differences are small, it is much more space-efficient to have a single set of clock tables, and fix those up at runtime instead. Hence provide three helpers: - Two helpers to NULLify core and module clocks that do not exist on some revisions (NULLified clocks are skipped during the registration phase), - One helper to reparent module clocks that have different clock parents.

In commit e66f81bb ("clk: sunxi-ng: Implement factors offsets"), the final formula of NKMP clocks' recalc_rate is refactored; however, the refactored formula broke the calculation due to some C language operand priority problem -- the priority of operand >> is lower than * and /, makes the formula being parsed as "(parent_rate * n * k) >> (p / m)", but it should be "(parent_rate * n * k >> p) / m". Add the pair of parentheses to fix up this issue. This pair of parentheses used to exist in the old formula. Fixes: e66f81bb ("clk: sunxi-ng: Implement factors offsets") Signed-off-by:

The timer-ids are wrong compared to the manual, probably due a simple copy-paste mistake from the otherwise very similar rk3288. And there are even more timers in the system than the ones wrongly listed here. Timer-Ids were unused both in clock-driver as well as devicetree till now, so fixing them won't break anything.

Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage. Signed-off-by:
