* rockchip: sdram: Fix register layout for LinuxJohn Keeping2016-07-25-7/+7
| | | | | | | | | | | | | | | | | | | | The ChromeOS kernel reads the RAM settings from PMU_SYS_REG2 and expects the bootloader to store the necessary information there. We're using the same register to pass the same information between the SPL and U-Boot but in a slightly different format. Change this to use the format expected by the Linux DMC driver so that the system doesn't hang in Linux by misconfiguring the RAM. This is almost the same as commit b5788dc ("rockchip: rk3288: correct sdram setting") which was reverted in commit b525556 ("Revert "rockchip: rk3288: correct sdram setting"") but parenthese have been added to apply the mask correctly when reading the "bw" setting and a couple of minor style issues have been fixed to keep check_patch.pl happy.

* rockchip: Use rockchip_get_clk() to obtain the SoC clockSimon Glass2016-07-25-1/+1
| | | | | | | | | | | | The current code picks the first available clock. In U-Boot proper this is the oscillator device, not the SoC clock device. As a result the HDMI display does not work. Fix this by calling rockchip_get_clk() instead.

* rockchip: Add a way to obtain the main clock deviceSimon Glass2016-07-25-0/+18
| | | | | | | | On Rockchip SoCs we typically have a main clock device that uses the Soc clock driver. There is also a fixed clock for the oscillator. Add a function to obtain the core clock. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | The function is very specific to the rk3288 in its arguments referencing the rk3288 cru and grf and every other rockchip soc has differing cru and grf registers.

* rockchip: sdram: Update the driver to support of-platdataSimon Glass2016-07-14-1/+39
| | | | | | | | | | | | Add support for of-platdata with rk3288 SDRAM initr. This requires decoding the of-platdata struct and setting up the device from that. Also the driver needs to be renamed to match the string that of-platdata will search for. The platform data is copied from the of-platdata structure to the one used by the driver. This allows the same code to be used with device tree and of-platdata. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: sdram: Move all DT decoding to ofdata_to_platdata()Simon Glass2016-07-14-30/+64
| | | | | | | | | It is more correct to avoid touching the device tree in the probe() method. Update the driver to work this way. Note that only SPL needs to fiddle with the SDRAM registers, so decoding the platform data fully is not necessary in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: syscon: Update to work with of-platdataSimon Glass2016-07-14-0/+38
| | | | | | | | | The syscon devices all end up having diffent driver names with of-platdata, since the driver name comes from the first string in the compatible list. Add separate device declarations for each one, and add a bind method to set up driver_data correctly. Signed-off-by: Simon Glass <sjg@chromium.org>
* clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

* Rename reset to sysresetStephen Warren2016-05-26-10/+10
| | | | | | | | | | | | | | The current reset API implements a method to reset the entire system. In the near future, I'd like to introduce code that implements the device tree reset bindings; i.e. the equivalent of the Linux kernel's reset API. This controls resets to individual HW blocks or external chips with reset signals. It doesn't make sense to merge the two APIs into one since they have different semantic purposes. Resolve the naming conflict by renaming the existing reset API to sysreset instead, so the new reset API can be called just reset.

| | | | | | | | | | | | | | | The DMC driver in v3.14 kernel[0] get the ddr setting from PMU_SYS_REG2, and it expects uboot to store the value using a same protocol. But now the ddr setting value is different with DMC, so if you enable the DMC, system would crash in kernel. Correct the sdram setting here, according to the requirements of kernel.
