* rockchip: rkpwm: fix the register sequenceKever Yang2016-10-01-1/+1
| | | | | | | | | Reference to kernel source code, rockchip pwm has three type, we are using v2 for rk3288 and rk3399, so let's update the register to sync with pwm_data_v2 in kernel. Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org>
* rockchip: rk3399: update PPLL and pmu_pclk frequencyKever Yang2016-10-01-2/+2
| | | | | | | | | | | | | | Update PPLL to 676MHz and PMU_PCLK to 48MHz, because: 1. 48MHz can make sure the pwm can get exact 50% duty ratio, but 99MHz can not, 2. We think 48MHz is fast enough for pmu pclk and it is lower power cost than 99MHz, 3. PPLL 676 MHz and PMU_PCLK 48MHz are the clock rate we are using internally for kernel,it suppose not to change the bus clock like pmu_pclk in kernel, so we want to change it in uboot.

* rockchip: Add a way to obtain the main clock deviceSimon Glass2016-07-25-0/+2
| | | | | | | | 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>
* cosmetic: rockchip: rk3288: rename rkclk_configure_cpuHeiko Stübner2016-07-25-1/+1
| | | | | | | | | | 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. So make that function naming explicit. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Simon Glass <sjg@chromium.org>
* rockchip: sdram: Move all DT decoding to ofdata_to_platdata()Simon Glass2016-07-14-8/+0
| | | | | | | | | 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: Update the sdram-channel property to support of-platdataSimon Glass2016-07-14-0/+6
| | | | | | | Add an extra byte so that this data is not byteswapped. Add a comment to the code to explain the purpose. Signed-off-by: Simon Glass <sjg@chromium.org>
* clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* rockchip: video: Add LVDS support in vop driverJacob Chen2016-03-14-0/+1
| | | | | | | | | | LVDS have a different display out mode, add code to get right flag. The vop_ip decide display device and the remote_vop_id decide which vop was being used. So we should use the remote_vop_id to set DCLK_VOP. Signed-off-by: Jacob Chen <jacob-chen@iotwrt.com> Acked-by: Simon Glass <sjg@chromium.org>

* rockchip: Tidy up the register-access macrosSimon Glass2016-01-21-3/+4
| | | | | | | | | These work reasonable well, but there are a few errors: - Brackets should be used to avoid unexpected side-effects - When setting bits, the corresponding upper 16 bits should be set also Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: video: Add a video-output driverSimon Glass2016-01-21-0/+349

* rockchip: video: Add a display driver for rockchip HDMISimon Glass2016-01-21-0/+456
| | | | | | | | | | | | Some Rockchip SoCs support HDMI output. Add a display driver for this so that these displays can be used on supported boards. Unfortunately this driver is not fully functional. It cannot reliably read EDID information over HDMI. This seems to be due to the clocks being incorrect - the I2C bus speed appears to be up to 100x slower than the clock settings indicate. The root cause may be in the clock logic.
