* clk: mvebu: ap-cpu-clk: Fix a memory leak in error handling pathsChristophe JAILLET2021-09-141-3/+11
| | | | | | | | | | | If we exit the for_each_of_cpu_node loop early, the reference on the current node must be decremented, otherwise there is a leak.

* clk: mvebu: ap-cpu-clk: Demote non-conformant kernel-doc headerLee Jones2021-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Not much effort has been put into this one. Demote it for the time being at least. Fixes the following W=1 kernel build warning(s): drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'ratio_state_reg' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'divider_mask' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'cluster_offset' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'force_mask' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'divider_offset' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'divider_ratio' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'ratio_offset' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'ratio_state_offset' not described in 'cpu_dfs_regs' drivers/clk/mvebu/ap-cpu-clk.c:52: warning: Function parameter or member 'ratio_state_cluster_offset' not described in 'cpu_dfs_regs' Cc: Michael Turquette <mturquette@baylibre.com> Cc: Stephen Boyd <sboyd@kernel.org> Cc: Julia Lawall <Julia.Lawall@inria.fr> Cc: Omri Itach <omrii@marvell.com> Cc: Gregory Clement <gregory.clement@bootlin.com> Cc: linux-clk@vger.kernel.org Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20210120093040.1719407-10-lee.jones@linaro.org Signed-off-by: Stephen Boyd <sboyd@kernel.org>

* drivers/clk: convert VL struct to struct_sizeStephen Kitt2019-11-081-2/+2
| | | | | | | | | | | | | | There are a few manually-calculated variable-length struct allocations left, this converts them to use struct_size.

* clk: mvebu: ap806-cpu: prepare mapping of AP807 CPU clockChristine Gharzuzi2019-09-171-20/+62
| | | | | | | | | | | | | | This patch allows same flow to be executed on chips with different register mappings like AP806 and, in the future, AP807. Note: this patch has no functional effect, and only prepares the driver for additional chips to be supported by retrieving the right device data depenging on the compatible property.

* clk: mvebu: add CPU clock driver for Armada 7K/8KGregory CLEMENT2019-08-081-0/+259
The CPU frequency is managed at the AP level for the Armada 7K/8K. The CPU frequency is modified by cluster: the CPUs of the same cluster have the same frequency. This patch adds the clock driver that will be used by CPUFreq, it is based on the work of Omri Itach <omrii@marvell.com>.
