[PATCH V4] clk: at91: PLL recalc_rate() now using cached MUL and DIV values

he past by 87e2ed338f1b ("clk: at91: fix recalc_rate implementation of PLL driver") but the bug was later re-introduced by 1bdf02326b71 ("clk: at91: make use of syscon/regmap internally"). Fixes: 1bdf02326b71 ("clk: at91: make use of syscon/regmap internally) Cc: Signed-off-by: Mar

actually being adjusted. Writing the multiplier and divider values to the peripheral fixes the bus running at half speed. Signed-off-by: Marcin Ziemianowicz --- drivers/clk/at91/clk-pll.c | 8 1 file changed, 8 insertions(+) diff --git a/drivers/clk/at91/clk-pll.c b/drivers/clk/at91/

[PATCH v2 1/2] clk: at91: Added more information logging.

I noticed that when debugging some USB clocking issue that there weren't many ways to tell what the state of the USB clocking system was. This adds a few logging statements to see what the relevant code is trying to do. Signed-off-by: Marcin Ziemianowicz --- drivers/clk/at91/clk-pll.c

[PATCH v2 0/2] clk: at91: Added more information logging

This is a series of patches which resolves set_rate() for the PLL not having any effect and therefore the USB Host port not working. Also, a few messages were added which may be helpful in the future when others are working with USB clocking. Changes since V1: Added patch set cover letter Shor
