2016-05-03clk: imx7d: fix ahb clock mux 1Stefan Agner1-1/+1
The clock parent of the AHB root clock when using mux option 1 is the SYS PLL 270MHz clock. This is specified in Table 5-11 Clock Root Table of the i.MX 7Dual Applications Processor Reference Manual. While it could be a documentation error, the 270MHz parent is also mentioned in the boot ROM configuration in Table 6-28: The clock is by default at 135MHz due to a POST_PODF value of 1 (=> divider of 2).

2016-04-06clk: imx: add ckil clock for i.MX7Gary Bisson1-1/+2
Add the necessary clock to use the ckil on i.MX7. Inspired from the following patch: https://github.com/boundarydevices/linux-imx6/commit/b80e8271 Signed-off-by: Troy Kisky <[email protected]> Signed-off-by: Gary Bisson <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
2015-12-02clk: imx: Replace clk error check with imx_check_clocks()Bai Ping1-4/+1
As we already have a 'imx_check_clocks' to do the clock error check, so cleanup the error check code. Signed-off-by: Bai Ping <[email protected]> Acked-by: Stephen Boyd <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
2015-12-02clk: imx: Add a virtual arm clk on i.mx7dBai Ping1-0/+6
Add a virtual arm clk to abstract the actual steps when changing the ARM core frequency.So we can using the 'cpufreq-dt' driver on i.MX7D/Solo. Signed-off-by: Bai Ping <[email protected]> Acked-by: Lucas Stach <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
2015-10-09clk: imx7d: add ADC root clockHaibo Chen1-0/+1
Add ADC root clock support in imx7d clock tree. Signed-off-by: Haibo Chen <[email protected]> Acked-by: Stephen Boyd <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
2015-09-25clk: imx7d: retain early UART clocks during kernel initLucas Stach1-0/+13
Make sure to keep UART clocks enabled during kernel init if earlyprintk or earlycon are active. Signed-off-by: Lucas Stach <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
2015-06-03ARM: imx: add imx7d clk tree supportFrank Li1-0/+860
Add i.MX7D clk tree support. Enable all clock to bring up imx7. Clock framework need be modified a little since imx7d change clock design. otherwise system will halt and block the other part upstream. All clock refine need wait for Dong Aisheng's patch clk: support clocks which requires parent clock on during operation Or other solution ready.
