When clock providers are added to the device tree after of_clk_init is called they are not added to the clock provider list. This makes that drivers such as i2c-xiic.c fail to init, as they may depend on the unadded clock provider.
We first introduce a new function clk.c that will check if a device_node is already a clock provider or not. Later we add two patches, one for clk-fixed-factor and another to clk-fixed-rate that make us of that function and also convert both drivers to module platform driver, but keeping all the previous functionality intact. v2: Changes proposed by: Stephen Boyd <[email protected]> -Add error check -CodeStyle on of_device_ide -Use builtin_platform_driver() Ricardo Ribalda Delgado (3): clk: Add new function of_clk_is_provider() clk: fixed-factor: Convert into a module platform driver clk: fixed-rate: Convert into a module platform driver drivers/clk/clk-fixed-factor.c | 75 +++++++++++++++++++++++++++++++++++++++--- drivers/clk/clk-fixed-rate.c | 71 ++++++++++++++++++++++++++++++++++++--- drivers/clk/clk.c | 20 +++++++++++ include/linux/clk-provider.h | 5 +++ 4 files changed, 162 insertions(+), 9 deletions(-) -- 2.8.1
