2019-04-23clk: core: replace clk_{readl,writel} with {readl,writel}Jonas Gorski
Now that clk_{readl,writel} is just an alias for {readl,writel}, we can switch all users of clk_* to use the accessors directly and remove the helpers.

2017-11-13clk: clk-xgene: Adjust six checks for null pointersMarkus Elfring
The script “checkpatch.pl” pointed information out like the following. Comparison to NULL could be written ... Thus fix the affected source code places. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

Omit extra messages for a memory allocation failure in these functions. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-07-21clk: Convert to using %pOF instead of full_nameRob Herring
Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

2016-10-28clk: xgene: Don't call __pa on ioremaped addressLaura Abbott
ioremaped addresses are not linearly mapped so the physical address can not be figured out via __pa. More generally, there is no guarantee that backing value of an ioremapped address is a physical address at all. The value here is only used for debugging so just drop the call to __pa on the ioremapped address.

2016-09-14clk: xgene: Add PMD clockHoan Tran
Add X-Gene PMD clock support. PMD clock is implemented for a single register field. Output rate = parent_rate * (denominator - scale) / denominator with - denominator = bitmask of register field + 1 - scale = values of register field For example, for bitmask is 0x7, denominator will be 8 and scale will be computed and programmed accordingly.

2016-03-03clk: xgene: Add missing parenthesis when clearing divider valueLoc Ho
In the initial fix for non-zero divider shift value, the parenthesis was missing after the negate operation. This patch adds the required parenthesis. Otherwise, lower bits may be cleared unintentionally.
