Ensure that unused I2C controllers are not activated, causing problems due to inappropriate pinmuxing or similar, by marking the controllers as disabled by default and requiring boards to explicitly enable those that are in use. Signed-off-by:

Mark Brown authored
Rather than requiring each board to explicitly disable the SPI controllers it is not using instead require boards to enable those that they are using. This is less work overall since normally at most one of the controllers is in use and avoids issues caused by inappropriate pinmuxing. Signed-off-by:

Exynos5420 SoC has per core thermal management unit. 5 TMU channels 4 for CPUs and 5th for GPU. This patch adds the device tree nodes to the DT device list. Nodes carry the misplaced second base address and the second clock to access the misplaced base address. Signed-off-by:

There is no need to use two cells for interrupt specifiers inside the MCT interrupt map, so this patch simplifies the map to use one cell. Signed-off-by:
-
Tomasz Figa authored
For MCT block compatible with "samsung,exynos4412-mct", that uses PPI interrupts for local timers, only one local interrupt needs to be specified, since it is a per-processor interrupt. This allows moving MCT node of Exynos4x12 SoCs back to common exynos4x12.dtsi, since they have the same set of interrupts to be specified, which was the only difference. Signed-off-by:

Tomasz Figa authored
MCT is not an interrupt controller and so there is no point for device tree nodes representing it to contain interrupt-controller and #interrupt-cells properties. Signed-off-by:
-
Tomasz Figa authored
This patch updates description of device tree bindings for Exynos MCT (multicore timers). Namely: - added note about simplified specification of local timer interrupts, when using single per-processor interrupt for all local timers, - changed first example that was incorrectly suggesting that global timer interrupts are optional, - simplified example interrupt map, - added example showing simplified local timer interrupt specification.

-
Tomasz Figa authored
All SoCs from Exynos4x12 series contain the MSHC block, so its node can be located in exynos4x12.dtsi. In addition, missing clock specifiers are added, generic SoC attributes are moved from board dts files to common dtsi file of SoC family and the node is renamed to a more generic name to follow node naming recommendations.

The device tree sent upstream for exynos5250-snow encoded the search key as CAPSLK. However in all ChromeOS kernels it is L_META. One can certainly have long debates about which it ought to be, but I'm proposing setting it to L_META because: * That's how _all_ ChromeOS kernels do it and will do it. * There is no L_META key on the board, so it's nice to have. * For those people who really want it to be caps lock, they can use xmodmap or somesuch.

When the exynos5250 device tree was sent upstream the keyboard mapping was missing the 2nd instance of the "\" key. There are two copies of the "\" because it simply has a different row and column on US and non-US keyboards.

According to board schematics, for HSMMC1 a GPIO line is used to detect card presence, while currently it is being configured for internal card detect line, which is multiplexed with card detect line of HSMMC0 and thus breaking it. This patch adds proper sdhci platform data setting card detect type to external GPIO and fixing operation of HSMMC0. Signed-off-by:

Total horizontal pixels = 1024 (x-res) + 80 (margin) + 48 (hsync) = 1152 Total vertical pixels = 600 (y-res) + 80 (margin) + 3 (vsync) = 683 Target pixel clock rate for refresh rate @60 Hz = 1152 * 683 * 60 = 47208960 Hz ~ 47.5 MHz Signed-off-by:

According to ePAPR, chapter 2.3.4, the status property has defined that it should be set to "disabled" when "the device is not presently operational, but it might become operational in the future". So this patch disable dwmmc node by "status = disabled" in SOC dts file and enable dwmmc node by "status = okay" in board specific dts file. Signed-off-by:
