ARM: dts: am43xx: fix SLEWCTRL_FAST pinctrl binding

2015-03-06T17:21:03+00:00

According to AM437x TRM, Document SPRUHL7B, Revised December 2014, Section 7.2.1 Pad Control Registers, setting bit 19 of the pad control registers actually sets the SLEWCTRL value to slow rather than fast as the current macro indicates. Introduce a new macro, SLEWCTRL_SLOW, that sets the bit, and modify SLEWCTRL_FAST to 0 but keep it for completeness. Current users of the macro (i2c, mdio, and uart) are left unmodified as SLEWCTRL_FAST was the macro used and actual desired state. Tested on am437x-gp-evm with no difference in software performance seen. Signed-off-by: Dave Gerlach Signed-off-by: Tony Lindgren

ARM: sunxi: DT: Convert the DTs to use a header for the pinctrl nodes

2015-01-21T08:58:57+00:00

The pinctrl nodes require some extra opaque arguments for the pull up and drive strength values. Introduce a new header file and convert the device trees to replace these opaque numbers by defines. Signed-off-by: Maxime Ripard

ARM: dts: Add minimal support for dm8168-evm

This allows booting the device with basic functionality. Note that at least on my revision c board the DDR3 does not seem to work properly and only some of the memory can be reliably used. Also, the mainline u-boot does not seem to properly initialize the ethernet, so I've been using the old TI u-boot at: http://arago-project.org/git/projects/?p=u-boot-omap3.git;a=summary Cc: Brian Hutchinson Signed-off-by: Tony Lindgren

pinctrl: dra: dt-bindings: Fix output pull up/down

2014-11-10T22:29:20+00:00

For PIN_OUTPUT_PULLUP and PIN_OUTPUT_PULLDOWN we must not set the PULL_DIS bit which disables the PULLs. PULL_ENA is a 0 and using it in an OR operation is a NOP, so don't use it in the PIN_OUTPUT_PULLUP/DOWN macros.

pinctrl: at91: add drive strength configuration

2014-09-05T08:32:06+00:00

The SAMA5 and SAM9x5 series both have drive strength options for the PIOs. This patch adds the ability to set one of three hardware options for drive strengths of low, medium or high for the each pin. The actual current output of the chip based on the setting is defined in the datasheets and varies per pins separate from banks and with supply voltage. This patch adds three new dt-bindings that allow setting the strength when configuring pins. By default, no change will be made to the drive strength of a pin from its reset value. Due to the difference between the register addresses of the SAMA5 and SAM9x5 series, a new sama5d3-pinctrl id was added.
