clk: clk-atlas6: fix return value check in atlas6_clk_init()

2020-08-21T08:53:06Z

[ Upstream commit 12b90b40854a8461a02ef19f6f4474cc88d64b66 ] In case of error, the function clk_register() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

clk: sirf: Don't reference clk_init_data after registration

2019-10-07T19:01:00Z

[ Upstream commit af55dadfbce35b4f4c6247244ce3e44b2e242b84 ] A future patch is going to change semantics of clk_register() so that clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid referencing this member here so that we don't run into NULL pointer exceptions.

clk: atlas7: fix noc/socket disconnect/reconnect for unit clks

2015-09-29T15:27:14Z

Power management on of NoC(Notwork On Chip) requires that disconnect and reconnect routine should been done during clk disable/enable. also there are different types of clocks, For NoC Macro clocks, write idle_bit and wait for hardward ACK; For Socket clocks, write idle_bit; For others, do nothing.

clk: atlas7: fix pll missed divide NR in fraction mode

2015-08-24T23:49:08Z

PLL VCO frequency is given by Fvco = Fref * 2 * NF / NR in integer-N mode, or by Fvco = Fref * SSN / NR in Spread Spectrum (fractional-N) mode. Thus fix the missing part of NR Signed-off-by: Guo Zeng Signed-off-by: Barry Song Signed-off-by: Stephen Boyd

clk: atlas7: fix integer overflow in dto rate calculation

2015-08-24T23:49:06Z

I cannot believe that I spend quite a lot time in finding this bug. It seems a pitfall people tend to fall in. In "int64 = int32 * int32", conversion from 32-bits to 64-bits comes after the multiplication. So this statement may not work as expected.
