* MLK-12576 imx: imx6ul: disable POR_B internal pull upAnson Huang2016-03-24-0/+9
| | | | | | | | | From TO1.1, SNVS adds internal pull up control for POR_B, the register filed is GPBIT[1:0], after system boot up, it can be set to 2b'01 to disable internal pull up. It can save about 30uA power in SNVS mode. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

| | | | | | | | | | | Fix 74LV OE gpio index. pinmux is correct, but gpio index is wrong, so gpio output will not have effect, since we use wrong GPIO5_IO18, but not correct GPIO5_IO8. And at the end of the initialization of 74lv init, should keep OE voltage level at LOW, but not high. Signed-off-by: Peng Fan <peng.fan@nxp.com>

* MLK-12483-3 mx6: Add a module fuse checkingYe Li2016-03-04-0/+385
| | | | | | | | | | | | | | | Implement a functionality to read the soc fuses and check if any module is fused. For fused module, we have to disable it in u-boot dynamically, and change the its node in FDT to "disabled" status before starting the kernel. In this patch, we implement the ft_system_setup for FDT fixup. This function will be called during boot process or by "fdt systemsetup" command. To enable the module fuse checking, two configurations must be defined: CONFIG_MODULE_FUSE CONFIG_OF_SYSTEM_SETUP Signed-off-by: Ye Li <ye.li@nxp.com>

| | | | | | | | | | | | | | | | | | | | On i.MX7D TO1.1, design team adds a mux cell at the CKE path to fix the suspend mode reset issue, but seems it add extra delay on CKE path, so CKE-CK timing violated. When DDR enters self-refresh or retention for long time(> 15seconds per testing on some boards), DDR data corruption occured, not able to decrease CKE delay, so we have to add extra delay on all other signals to balance it. DDR script needs to be fine-tuned according to this hardware change. For DDR3, since the timing margin is not good, we have to decrease the DDR frequency from 533Mhz to 400Mhz.

| | | | | | | | | | | | | | | | | Introudce wp_enable. If want to check WPSPL, then in board code, need to set wp_enable to 1. Take i.MX6UL for example, to some boards, they do not use WP singal, so they does not configure USDHC1_WP_SELECT_INPUT, and its default value is 0(GPIO1_IO02). However GPIO1_IO02 is muxed for i2c usage and SION bit set. So USDHC controller can always get wp signal and WPSPL shows write protect and blocks driver continuing. This is not what we want to see, so add wp_enable, and if set to 0, just omit the WPSPL checking and this does not effect normal working of usdhc controller.

A enet2_en pin is added for isolating enet2 signals with EPDC, we also add support for enet2. 3. pin6 of 74LV output is changed for CSI PWDN. Set output to high to power down it. This patch also tries to get the board id and apply changes according with it. Since current RevB board does not burn GP1 fuse for board id, we have to check the TO rev instead even it is not very exact. Will update this if any new way implemented.
