Currently we get a nasty error message if the cpu clock can't be changed: DDRC is clocked by PLL1, can't switch CPU clockinitcall vf610_switch_cpu_clock+0x1/0x198 failed: Invalid argument So let's do the following: - factor out the check from vf610_switch_cpu_clock_to_500mhz() and vf610_switch_cpu_clock_to_400mhz - if clock can't be changed, don't treat it as an error - don't call clock notifier chain if clock can't be changed - add trailing newline to the warning message Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Heiner Kallweit authored on 27 Apr 2019 Sascha Hauer committed on 29 Apr 2019

2019-04-10	05e69a1 Browse files » clk: socfpga: fix compiler warnings for Cyclone5 ... When building for Cyclone5 SoCFPGA, the socfpga_a10_pll_init(), socfpga_a10_perith_init() and socfpga_a10_gate_init() functions are defined as dummy functions returning ERR_PTR(-ENOSYS). They are defined with external linkage. With '-Wmissing-prototypes' GCC warns about externally linked function definitions with no preceding prototype. Define them as 'static inline' to avoid the compiler warnings. (Note: Arria10 uses non-dummy versions of these functions declared 'extern' but defined elsewhere.)

2019-03-18	a3167da Browse files » clk: add ZynqMP clock driver ... The ZynqMP has a platform management unit (PMU) that is responsible for managing the clocks. Therefore, the clock driver uses the firmware driver to control the clocks. The Barebox driver is based on the Linux driver, but contains deviations to make the driver more readable and more consistent.

This is mostly an adoption of the corresponding Linux driver. This is tested on the LS1046a SoC.

2019-02-25	af5383e Browse files » clk: at91: update to PMC bindings ... Based on kernel 5.0-rc6 update at91 clk support to match the new PMC bindings. Manually added all changes done in the kernel from 4.9-rc3 to 5.0-rc6. New drivers required was added as seperate commits. This includes dt-compat code required to support at91sam5d3, as this is not yet ported to use the new PMC bindings. clk-programmable saw some extra changes - it had never been bulit. It is used only by at91sama5d2 - and barebox has no board support for this cpu (yet). The CONFIG_SOC symbols is used to select the relevant drivers. CONFIG_SOC_SAM9 selects several drivers, and in the future this can be split to keep the image size down. In the kernel CLK_OF_DECLARE_DRIVER() can be used for a two step init. In barebox this is a simple one step init. It was added to have less differences between the kernel and the barebox versions of the drivers.
