* arm: imx6: novena, gw_ventana: Fix use of pfuze100 bit definitionsMarek Vasut2015-12-01-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The following patch changed the PFUZE100 swbst register bit definitions and broke PMIC configuration on multiple boards, at least on the novena and gw_ventana. This patch fixes it. commit 8fa46350a4c7dca7710362f6c871098557b934ad Author: Peng Fan <Peng.Fan@freescale.com> Date: Fri Aug 7 16:43:45 2015 +0800 power: regulator: add pfuze100 support Signed-off-by: Marek Vasut <marex@denx.de> Cc: Fabio Estevam <fabio.estevam@freescale.com> Cc: Peng Fan <Peng.Fan@freescale.com> Cc: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Tim Harvey <tharvey@gateworks.com> Cc: Vagrant Cascadian <vagrant@aikidev.net> Reviewed-by: Przemyslaw Marczak <p.marczak@samsung.com> Tested-by: Vagrant Cascadian <vagrant@aikidev.net> Reviewed-by: Peng Fan <Peng.Fan@freescale.com> Acked-by: Tim Harvey <tharvey@gateworks.com>

* imx: mx6: ddr init MMDC according to ddr_typePeng Fan2015-09-02-0/+1
| | | | | | | | | | | | | | | | | To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper. The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg when ddr_type is for DDR3. Later we can use ddr_type to initialize MMDC for LPDDR2. Initialize ddr_type for different boards which enable SPL.

Additionally the 'gsc wd' command can be used to enable or disable the watchdog with the following usage: gsc wd enable [30|60] gsc wd disable Note that the GSC registers are battery-backed by the GSC coincell so once eanbled, they remain enabled across power-cycles or until either the GSC firmware has been updated or FLASH has been re-programmed by the Gateworks JTAG adapter.

| | | | | | | | | | | | | The IMX6 Datasheets specifies that when the IMX6 LDO is enabled (internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive) and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it up to the kernel to implement a regulator driver for the LTC3676 and put the LDO's in bypass mode which allows us to drop the voltages by 125mV respectively.
