2018-02-24rockchip: clk: rk3399: handle set_rate/get_rate for PLL_PPLLPhilipp Tomsich
The device-tree node for the PMU clk controller assigns to its parent (i.e. PLL_PPLL) even though this clock currently is set up statically by an init-function. In order to avoid unexpected failures, a simple implementation of set_rate (which accepts requests, but notifies the caller of the preset frequency in its return value) and get_rate (which always returns the preset frequency) are added. Note that this is required for the RK808 PMIC to probe successfully on the RK3399-Q7, following the support for the assigned-clocks property.

2018-02-24rockchip: clk: rk3368: handle clk_enable requests for GMACPhilipp Tomsich
Since commit ba1f96672522 ("net: designware: add clock support"), the designware GMAC driver enables all referenced clocks. While this is a no-op for the RK3368 during boot-up (reset behaviour has all the clock gates open anyway), we still need to handle the clock-ids passed in the enable op of the clock-driver and return a success. This change extends the RK3368 clk driver to: (a) provide a enable op (b) signals success to the caller when the clocks for the GMAC are enabled (no actual action is necessary as the gates are open after reset) References: commit ba1f96672522 ("net: designware: add clock support") Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Klaus Goger <klaus.goger@theobroma-systems.com>

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.

2017-09-15dtoc: Add support for 32 or 64-bit addressesSimon Glass
When using 32-bit addresses dtoc works correctly. For 64-bit addresses it does not since it ignores the #address-cells and #size-cells properties. Update the tool to use fdt64_t as the element type for reg properties when either the address or size is larger than one cell. Use the correct value so that C code can obtain the information from the device tree easily. Alos create a new type, fdt_val_t, which is defined to either fdt32_t or fdt64_t depending on the word size of the machine. This type corresponds to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types since they are defined to phys_addr_t and phys_size_t which use 'unsigned long' in the 32-bit case, rather than 'unsigned int'. Add tests for the four combinations of address and size values (32/32, 64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368 which now need to use the new fdt_val_t type.

2017-08-13rockchip: clk: rk3368: implement MMC/SD clock reparentingPhilipp Tomsich

This change rewrites the MMC/SD clock generation to: * always generate a clock less-than-or-equal to the requested clock * support reparenting among the CPLL, GPLL and OSC24M parents to generate the highest clock that does not exceed the requested rate In addition to this, the Linux DTS uses HCLK_MMC/HCLK_SDMMC instead of SCLK_MMC/SCLK_SDMMC: to match this (and to ensure that clock setup always works), we adjust the driver appropriately.

These should not be modified by the SPL stage, if we intend to return to the BootROM for chain booting the next stage. This commit changes the clock initialisation to not change CPLL/GPLL before returning to the BootROM (i.e. in TPL). As it's safe to change these settings if we no longer intend to return to U-Boot, we'll run the full PLL setup a little later (i.e. in SPL).
