pinctrl: nxp: DM_FLAG_PRE_RELOC by default

2019-10-08T14:36:37Z

For NXP SoCs we have to set pinmux configuration ASAP (ideally before relocation) to get serial console working. Without this we miss almost the half of output (U-boot version, CPU defails, Reset cause, DRAM details etc.). To achieve this we need to force appropriate pinctrl drivers to get probed before relocation.

pinctrl: imx: use devfdt_get_addr_size_index

2019-10-08T14:35:16Z

fdtdec_get_addr_size could not parse addr/size correctly is using address-cells 2 and size-cells 2 on an ARM32 SoC. So switch to use devfdt_get_addr_size_index. Signed-off-by: Peng Fan

pinctrl: mxs: Add support for i.MX2[38] mxs pinctrl driver

2019-07-19T12:57:14Z

The code responsible for setting proper values in the MUX registers (in the mxs_pinctrl_set_state()) has been ported from Linux kernel - SHA1: 17bb763e7eaf tag v5.1.11 from linux-stable. As the pinctrl node in the imx28.dtsi file has gpio pins nodes as subnodes, it was necessary to use 'dm_scan_fdt_dev()' (as a .bind method) to also make them 'visible' by the DM's "gpio_mxs" driver.

pinctrl: imx: Define imx6_pinctrl_soc_info in .data section

2019-06-11T08:43:00Z

This commit is necessary to be able to re-use the pinctrl code in early SPL to properly configure pins. The problem is that those "static" structures (without explicit initialization) are placed in the SDRAM area, which corresponds to u-boot proper (not even SPL). Hence, when one wants to configure pins before relocation via DTS/DM, the board hangs (imx6q SoC powered one) as only OCRAM area is available (0x009xxxxx). This commit prevents from this issue by moving the imx6_pinctrl_soc_info structure to data section (from BSS). Signed-off-by: Lukasz Majewski Reviewed-by: Peng Fan

pinctrl: imx: Fix select input issue

2019-01-28T19:35:47Z

The pinctrl supports to set any bit in input register on iMX6 if the MSB of input value is 0xff. But the driver uses signed int for input value, so when executing the codes below, it won't meet. Because this is arithmetic right shift. if (input_val >> 24 == 0xff) Fix the issue by changing the input_val, config_val and mux_mode to u32.

pinctrl: Remove DM_FLAG_PRE_RELOC flag in various drivers

2018-11-14T17:16:28Z

When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng Reviewed-by: Simon Glass
