The 5P35023 is a VersaClock programmable clock generator and it provides 6 clk outputs {diff2, diff1, se3, se2, se1 and refin}. It has an internal OTP memory allows the user to store the configuration in the device. After power up, the user can change the device register settings through the I2C interface when I2C mode is selected. This driver is for overriding OTP default values during boot based on a full register map from DT, and also minimal support to change the parent of a output clock. The motivation for developing this driver is for supporting 48KHz playback/record with audio codec on RZ/G2L SMARC EVK. On RZ/G2L SMARC EVK, By default audio mclk is connected to 11.2896 MHz clk which is multiple of 44.1KHz. Please see the below default OTP configuration of Dividers connected to output clocks. DIV3 12.2880 MHz DIFF2--> Audio clk2 DIV5 11.2896 MHz SE1 --> Audio clk1 DIV5 11.2896 MHz SE2 --> Audio mck DIV4 12 MHz SE3 --> This clk Not used DIV1 25 MHz DIFF1-->Ethernet clk Ref1-> 24MHz With this setup, we won't be able to do 48KHz playback/record on audio codec, as mck is always connected to 11.2896MHz clk. But by programming the i2c, we can make use of DIV4 to generate 12.2880 MHz and make that as parent of SE2 and there by supporting 48KHz playback/record. A block diagram with modification can be find here[1] [1]https://paste.pics/a253ce7cdc8720c3b5eb6953b97b25ff DIV3 12.2880 MHz DIFF2--> Audio clk2 DIV5 11.2896 MHz SE1 --> Audio clk1 DIV5 11.2896 MHz | SE2 --> Audio mck DIV4 12.2880 MHz | DIV2 12 MHz SE3 --> This clk Not used DIV1 25 MHz DIFF1--> Ethernet clk Ref1-> 24MHz The driver can read a full register map from the DT, and will use that register map to initialize the clk generator when the system boots. and later, based on sampling rate, it switches the parent of SE2 and support both 44.1 and 48 KHz playback/record at run time. v4->v5: * Added missing .determine_rate() for muxes * Fixed smatch warning: replace divide condition 'req->best_parent_rate / req->rate' with 'req->best_parent_rate >= req->rate' Reported-by: kernel test robot <lkp@intel.com> and Reported-by: Dan Carpenter <error27@gmail.com> v3->v4: * Fixed the warning reported by kernel test robot. * Added error check for devm_clk_hw_register_fixed_factor_* in probe(). v2->v3: * Added Rb tag from Krzysztof Kozlowski * Removed | from Link to data sheet. * Dropped stray blank line from example. * Updated example section for assigned-clocks to mach same alignment with assigned-clock-rates. This is trivial change so retained the Rb tag. * Updated copy right information. * Removed .name from parent data and started using index or struct clk_hw. * Dropped vc3_clk_out_ops and started using fixed factor clocks for output clk. * Dropped vc3_divider_type_parse_dt function. * Dropped struct vc3_driver_data * Updated the dtsi changes for RZ/G2LC and RZ/G2{UL, Five}. RFC->v2: * Renamed the filename to match with compatible * Added maintainers entry after title * Removed the wrapping for the link to data sheet. * Removed reg description * Removed clock names * Replaced minItems->maxItems in renesas,settings property * Dropped assigned-clocks, assigned-clock-rates * Dropped renesas,clock-divider-read-only and renesas,clock-flags * Drooped clock handle part from example * Dropped reg from example. * Dropped consumer example * Dropped header file <linux/clk.h> and removed all consumer api's * struct clk_parent_data used for assigning the parent names. * Replaced initpointer->const init pointer in vc3_clk_register * Replaced of_clk_add_hw_provider with devm_clk_add_hw_provider * Dropped vc3_remove() callback.
