* imx: clock: gate clk before changing pix clk muxPeng Fan2016-12-16-1/+1
| | | | | | | | | | | The LCDIF Pixel clock mux is not glitchless, so need to gate before changing mux. Also change enable_lcdif_clock prototype with a new input parameter to indicate disable or enable. Signed-off-by: Peng Fan <peng.fan@nxp.com> Cc: Stefano Babic <sbabic@denx.de>

* mx6ul_14x14_evk: Pass refsel and refr fields to avoid hangFabio Estevam2016-09-06-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | When running a NXP 4.1 kernel with U-Boot mainline on a mx6ul-evk, we observe a hang when going into the lowest operational point of cpufreq. This hang issue does not happen on the NXP U-Boot version. After comparing the SPL DDR initialization against the DCD table from NXP U-Boot, the key difference that causes the hang is the MDREF register setting: DATA 4 0x021B0020 0x00000800 ,which means: REF_SEL = 0 --> Periodic refresh cycle: 64kHz REFR = 1 ---> Refresh Rate - 2 refreshes So adjust the MDREF initialization for mx6ul_evk accordingly to fix the kernel hang issue at low bus frequency.

* mx6: ddr: Allow changing REFSEL and REFR fieldsFabio Estevam2016-09-06-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently MX6 SPL DDR initialization hardcodes the REF_SEL and REFR fields of the MDREF register as 1 and 7, respectively for DDR3 and 0 and 3 for LPDDR2. Looking at the MDREF initialization done via DCD we see that boards do need to initialize these fields differently: $ git grep 0x021b0020 board/ board/bachmann/ot1200/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/ccv/xpress/imximage.cfg:DATA 4 0x021b0020 0x00000800 /* MMDC0_MDREF */ board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x7800 board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6qp.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6dlsabresd.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6slevk/imximage.cfg:DATA 4 0x021b0020 0x00001800 board/freescale/mx6sxsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/freescale/mx6sxsabresd/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800 So introduce a mechanism for users to be able to configure REFSEL and REFR fields as needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to support mx6ul_9x9_evk board based on mx6ul_14x14_evk, the difference between mx6ul 9x9 evk and mx6ul 14x14 evk are: 1. mx6ul 9x9 evk use pfuze3000, while mx6ul 14x14 evk use DCDC. 2. mx6ul 9x9 evk supports 256MB LPDDR2, while mx6ul 14x14 evk supports 512MB DDR3 3. mx6ul_9x9_evk use 9x9 package, while mx6ul_14x14_evk use 14x14 package. This patch add the following: 1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size() 2. Introduce a macro is_mx6ul_9x9_evk using CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work, so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with mx6ul_14x14_evk. And we have no way to dymaically checking this chip is 9x9 or 14x14. 3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations. POWER related configurations also effect for mx6ul_14x14_evk. But power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk. 4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM configurations. 5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file according to board_rev and board_name. 6. Add TARGET_MX6UL_9X9_EVK Kconfig entry Boot Log: U-Boot SPL 2015.10-rc2-00356-g536ce34 (Sep 06 2015 - 12:22:53) reading u-boot.img reading u-boot.img U-Boot 2015.10-rc2-00356-g536ce34 (Sep 06 2015 - 12:22:53 +0800) CPU: Freescale i.MX6UL rev1.0 792 MHz (running at 396 MHz) CPU: Commercial temperature grade (0C to 95C) at 41C Reset cause: POR Board: MX6UL 9x9 EVK I2C: ready DRAM: 256 MiB PMIC: PFUZE3000 DEV_ID=0x30 REV_ID=0x11 MMC: FSL_SDHC: 0, FSL_SDHC: 1 In: serial Out: serial Err: serial Net: FEC1 Hit any key to stop autoboot: 0 Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Cc: Stefano Babic <sbabic@denx.de>
