2019-10-22drivers: clk: Add a managed API to get clocks from the device-treeJean-Jacques Hiblot
Add devm_clk_get(), devm_clk_get_optional() to get clocks from the device-tree. The clocks is automatically released and the data structure freed when the device is unbound. Also add devm_clk_put() to release the clock and free the data structure manually. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>

Prepare the way for a managed CLK API by handling NULL pointers without crashing nor failing. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-10-22clk: Add support for I2C clocks on NXP's imx6q SoC which use CCFLukasz Majewski
This change adds support for I2C clock modeled in CCF. This code intention is to only enable those clocks in the I2C driver with default settings. For that reason the "busy" versions of clocks reuse the generic approach and would need to be updated when one wants to adjust the I2C clock frequency in U-Boot.

2019-10-22clk: Fix error check in clk_set_default_parents()Jean-Jacques Hiblot

2019-10-11clk: cdce9xx: add support for cdce9xx clock synthesizerTero Kristo
Add support for CDCE913/925/937/949 family of devices. These are modular PLL-based low cost, high performance, programmable clock synthesizers, multipliers and dividers. They generate up to 9 output clocks from a single input frequency. The initial version of the driver does not support programming of the PLLs, and thus they run in the bypass mode only. The code is loosely based on the linux kernel cdce9xx driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>

2019-08-26Kconfig: Varios: Fix more SPL, TPL dependenciesAdam Ford
Several options are presenting themselves on a various boards where the options are clearly not used. (ie, SPL/TPL options when SPL or TPL are not defined) This patch is not attempting to be a complete list of items, but more like low hanging fruit. In some instances, I wasn't sure of DM was required, so I simply made them SPL or TPL. This patch attempts to reduce some of the menuconfig noise by defining dependencies so they don't appear when not used. Signed-off-by: Adam Ford <aford173@gmail.com>

2019-08-22clk: prograte clk enable/disable to parentPeng Fan
On i.MX8MM, thinking such as clk path OSC->PLL->PLL GATE->CCM ROOT->CCGR GATE->Device Only enabling CCGR GATE is not enough, we also need to enable PLL GATE to make sure the clk path work. So when enabling CCGR GATE, we could prograte to enabling PLL GATE to make life easier. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2019-08-22clk: introduce enable_countPeng Fan

Introduce enable_count to track the clk enable/disable count when clk_enable/disable for CCF. And Initialize enable_count to 0 when register the clk. And clk tree dump with enable_count will be supported, it will be easy for us to check the clk status with enable_count Signed-off-by: Peng Fan <peng.fan@nxp.com>
