clk: sprd: return correct type of value for _sprd_pll_recalc_rate

2020-06-24T15:48:58+00:00

[ Upstream commit c2f30986d418f26abefc2eec90ebf06716c970d2 ] The function _sprd_pll_recalc_rate() defines return value to unsigned long, but it would return a negative value when malloc fail, changing to return its parent_rate makes more sense, since if the callback .recalc_rate() is not set, the framework returns the parent_rate as well.

clk: sprd: don't gate uart console clock

2020-04-13T19:20:07+00:00

Don't gate uart1_eb which provides console clock, gating that clock would make serial stop working if serial driver didn't enable that explicitly.

clk: sprd: fix to get a correct ibias of pll

2020-04-03T01:07:58+00:00

The current driver is getting a wrong ibias index of pll clocks from number 1. This patch fix that issue, then getting ibias index from 0.

Some SC9863a clock nodes would be the child of a syscon node, clocks can use the regmap of syscon device directly for this kind of cases. Signed-off-by: Chunyan Zhang Link: https://lkml.kernel.org/r/20200304072730.9193-7-zhang.lyra@gmail.com Signed-off-by: Stephen Boyd

clk: sprd: Add macros for referencing parents without strings

2020-03-25T02:03:57+00:00

With the new clk parenting code, clk_init_data was expanded to include .parent_hws and .parent_data, for clk drivers to specify parents without name strings of clocks. Also some macros were added for using these two items to reference clock parents. Based on that to expand macros for sprd clocks: - SPRD_*_DATA, take an array of struct clk_parent_data * as its parents which should be a combination of .fw_name (devicetree clock-names), .hw (pointers to a local struct clk_hw). - SPRD_*_HW, take a local struct clk_hw pointer, instead of a string, as its parent. - SPRD_*_FW_NAME, take a string of clock-names decleared in the device tree as the clock parent.
