2020-02-14clk: imx: composite-8m: add imx8m_clk_hw_composite_corePeng Fan2-6/+25
There are several clock slices, current composite code only support bus/ip clock slices, it could not support core slice. So introduce a new API imx8m_clk_hw_composite_core to support core slice. To core slice, post divider with 3 bits width and no pre divider. Other fields are same as bus/ip slices. Add a flag IMX_COMPOSITE_CORE for the usecase.

2020-02-12clk: at91: usb: continue if clk_hw_round_rate() return zeroClaudiu Beznea1-0/+3
clk_hw_round_rate() may call round rate function of its parents. In case of SAM9X60 two of USB parrents are PLLA and UPLL. These clocks are controlled by clk-sam9x60-pll.c driver. The round rate function for this driver is sam9x60_pll_round_rate() which call in turn sam9x60_pll_get_best_div_mul(). In case the requested rate is not in the proper range (rate < characteristics->output[0].min && rate > characteristics->output[0].max) the sam9x60_pll_round_rate() will return a negative number to its caller (called by clk_core_round_rate_nolock()). clk_hw_round_rate() will return zero in case a negative number is returned by clk_core_round_rate_nolock(). With this, the USB clock will continue its rate computation even caller of clk_hw_round_rate() returned an error. With this, the USB clock on SAM9X60 may not chose the best parent. I detected this after a suspend/resume cycle on SAM9X60.

2020-02-12clk: Move rate and accuracy recalc to mostly consumer APIsStephen Boyd1-24/+24
There's some confusion about when recalc is done for the rate and accuracy clk consumer APIs in relation to the prepare lock being taken. Oddly enough, we take the lock again in debugfs APIs so that we can call the internal "clk_core" APIs to get these fields with any necessary recalculations. Instead of having this confusion, let's introduce a recalc variant of these two consumer APIs as internal helpers and call them from the consumer APIs and the debugfs code so that we don't take the lock more than once.

Some lines are getting long in this function. Let's move 'parent' up to the top of the function and use it in many places whenever there is a parent for a clk.

2020-02-12clk: Don't cache errors from clk_ops::get_phase()Stephen Boyd1-16/+32
We don't check for errors from clk_ops::get_phase() before storing away the result into the clk_core::phase member. This can lead to some fairly confusing debugfs information if these ops do return an error. Let's skip the store when this op fails to fix this. While we're here, move the locking outside of clk_core_get_phase() to simplify callers from the debugfs side.

It's nicer to use ARRAY_SIZE instead of hardcoding. Had we always been doing this it would have prevented a previous bug.
