clk: armada-370: fix refcount leak in a370_clk_init() The of_find_compatible_node() returns a node pointer with refcount incremented, but there is the lack of use of the of_node_put() when done. Add the missing of_node_put() to release the refcount.

clk: mvebu: flag the crypto clk as CLK_IGNORE_UNUSED The crypto SRAM, used by the armada 370 cpuidle code to workaround a bug in the BootROM code, requires the crypto clk to be up and running. Flag the crypto clk as IGNORE_UNUSED until we add the proper infrastructure to define the crypto SRAM in the DT and reference the crypto clk in this SRAM node.

clk: mvebu: add missing CESA gate clk Even if not documented in the datasheet, the Armada 370 SoC can actually gate the CESA (crypto engine) clock. Add an entry in the gating_desc table to be able to reference the CESA gateclk in the crypto node.

clk: mvebu: armada-370: Fix timer drift caused by the SSCG deviation This commit activates the SSCG deviation correction for the Armada 370. It uses the optional function introduced by the commit "clk: mvebu: Fix clk frequency value if SSCG is enabled". Without this fix the deviation measured on a Mirabox was of a few second each hour, whereas with this fix it was reduced at around 50ppm (around 4s per day).

clk: mvebu: armada-370: maintain clock init order Init order of CLK_OF_DECLARE'd drivers depends on compile order. Unfortunately, clk_of_init does not allow drivers to return errors, e.g. -EPROBE_DEFER if parent clocks have not been registered, yet. To avoid init order woes for MVEBU clock drivers, we take care of proper init order ourselves. This patch joins core-clk and gating-clk init to maintain proper init order.

clk: armada-370: fix tclk frequencies This patch fixes the tclk frequency array for the Armada-370 SoC. This bug has been introduced by commit 6b72333d ("clk: mvebu: add Armada 370 SoC-centric clock init"). A wrong tclk frequency affects the following drivers: mvsdio, mvneta, i2c-mv64xxx and mvebu-devbus. This list may be incomplete. About the mvneta Ethernet driver, note that the tclk frequency is used to compute the Rx time coalescence. Then, this bug harms the coalescence configuration and also degrades the networking performances with the default values.

clk: mvebu: add Armada 370 SoC-centric clock init This is moving core clock and clock gating init for Armada 370 to its own file and adds a Kconfig option. Also init functions are added and declared so they get called on of_clk_init.
