clk: at91: fix clk_programmable_set_parent()

2016-07-19T00:45:41Z

Since commit 1bdf02326b71e ("clk: at91: make use of syscon/regmap internally"), clk_programmable_set_parent() is always selecting the first parent (AKA slow_clk), no matter what's passed in the 'index' parameter. Fix that by initializing the pckr variable to the index value.

A bunch of fixes. Some for the newly added rk3399 clock tree, some concerning error handling and initialization and a revert of the mmc-phase clock initialization, as this could conflict with the bootloader setting of this clock and a real solution to initing the phase correctly from dw_mmc went in as fix for 4.7 through the mmc tree. * tag 'v4.7-rockchip-clk-fixes1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip: clk: rockchip: release io resource when failing to init clk on rk3399 clk: rockchip: fix cpuclk registration error handling clk: rockchip: Revert "clk: rockchip: reset init state before mmc card initialization" clk: rockchip: fix incorrect parent for rk3399's {c,g}pll_aclk_perihp_src clk: rockchip: mark rk3399 GIC clocks as critical clk: rockchip: initialize flags of clk_init_data in mmc-phase clock

clk: Fix return value check in oxnas_stdclk_probe()

2016-06-21T00:00:29Z

In case of error, the function syscon_node_to_regmap() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

clk: sunxi: remove unused variable

2016-06-16T07:18:29Z

The only use of the local num_parents variable was remove, so we now get a warning: drivers/clk/sunxi/clk-sun4i-tcon-ch1.c: In function 'tcon_ch1_get_parent': drivers/clk/sunxi/clk-sun4i-tcon-ch1.c:82:6: error: unused variable 'num_parents' [-Werror=unused-variable] This removes the variable.

clk: sunxi: display: Add per-clock flags

2016-06-10T09:49:47Z

The TCON channel 0 clock that is the parent clock of our pixel clock is expected to change its rate depending on the resolution we want to output in our display engine. However, since it's only a mux, the only way it can do that is by changing its parents rate. Allow to give flags in our display clocks description, and add the CLK_SET_RATE_PARENT flag for the TCON channel 0 flag.

clk: sunxi: tcon-ch1: Do not return a negative error in get_parent

2016-06-10T09:49:15Z

get_parent is supposed to return an unsigned 8 bit integer, so returning -EINVAL is a bad idea. Remove it. Reported-by: Dan Carpenter Acked-by: Chen-Yu Tsai Signed-off-by: Maxime Ripard

clk: rockchip: release io resource when failing to init clk on rk3399

2016-06-03T13:36:49Z

We should call iounmap to relase reg_base since it's not going to be used any more if failing to init clk. This was missing on the newly added rk3399 clock tree. Signed-off-by: Shawn Lin Signed-off-by: Heiko Stuebner

clk: nxp: Select MFD_SYSCON for creg driver

2016-06-01T22:14:06Z

Commit 378523d15003 ("clk: add lpc18xx creg clk driver") added a new clock driver but missed the proper MFD_SYSCON select. Fix it. Fixes: 378523d15003 ("clk: add lpc18xx creg clk driver") Signed-off-by: Ezequiel Garcia Acked-by: Joachim Eastwood Signed-off-by: Stephen Boyd

clk: microchip: Remove CLK_IS_ROOT

2016-06-01T21:52:54Z

This flag is a no-op now (see commit 47b0eeb3dc8a "clk: Deprecate CLK_IS_ROOT", 2016-02-02) so remove it. Cc: Purna Chandra Mandal Cc: Ralf Baechle Cc: Signed-off-by: Stephen Boyd
