Merge tag 'imx-clk-fixes-4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into clk-next

2016-05-12T21:48:26+00:00

Pull some non-critical i.MX clk fixes from Shawn Guo: * Fix the commit 3713e3f5e927 ("clk: imx35: define two clocks for rtc") which messed up the clock enumeration when adding new clock. * tag 'imx-clk-fixes-4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: dts: imx35: restore existing used clock enumeration clk: imx6q: fix typo in CAN clock definition

clk: imx7d: fix ahb clock mux 1

2016-05-03T12:35:38+00:00

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).

clk: imx: return correct frequency for Ethernet PLL

2016-04-27T02:02:04+00:00

The i.MX 7 designs Ethernet PLL provides a 1000MHz reference clock. Store the reference clock in the clk_pllv3 structure according to the PLL type. Signed-off-by: Stefan Agner Signed-off-by: Shawn Guo

ARM: dts: imx35: restore existing used clock enumeration

2016-04-18T04:37:21+00:00

A new element got inserted into enum mx35_clks with commit 3713e3f5e927 ("clk: imx35: define two clocks for rtc"). This insertion shifted most nummerical clock assignments to a new nummerical value which in turn rendered most hardcoded nummeric values in imx35.dtsi incorrect. Restore the existing order by moving the newly introduced clock to the end of the enum. Update the dts documentation accordingly.

clk: imx6q: fix typo in CAN clock definition

2016-04-13T07:27:15+00:00

commit ee36027427c7 ("clk: imx: Add clock support for imx6qp") introduced a regression due to a subtle typo in the 'can_root' clock definition. The effect is that trying to configure the bitrate of the can interfaces fails with -EDOM or produces a division by zero error due to the clock_freq of the can serial clock being reported as '0'.

clk: imx: vf610: add TCON ipg clock

2016-04-12T01:22:17+00:00

Add the ipg (bus) clock for the TCON modules (Timing Controller). This module is required by the new DCU DRM driver, since the display signals pass through TCON. Signed-off-by: Stefan Agner Signed-off-by: Shawn Guo

clk: imx: vf610: fix DCU clock tree

2016-04-12T01:21:53+00:00

Similar to an earlier fix for the SAI clocks, the DCU clock hierarchy mixes the bus clock with the display controllers pixel clock. Tests have shown that the gates in CCM_CCGR3/9 registers do not control the DCU pixel clock, but only the register access clock (bus clock). Fix this by defining the parent clock of VF610_CLK_DCUx to be the bus clock (ipg_bus). Since the clock has not been used far, there are no further changes needed.

clk: imx: add ckil clock for i.MX7

2016-04-06T09:04:26+00:00

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 Signed-off-by: Gary Bisson Signed-off-by: Shawn Guo

clk: imx: vf610: add suspend/resume support

2016-03-31T09:02:06+00:00

The clock register are lost when enterying LPSTOPx, hence provide suspend/resume functions restoring them. The clock gates get restored by the individual driver, hence we do not need to restore them here. Signed-off-by: Stefan Agner Signed-off-by: Shawn Guo
