Subject: [PATCHv2] ARM: dts: imx6ull: add UART5 input select register definitions
Date: Thu, 29 Mar 2018 00:22:23 +1000 [thread overview]
Message-ID: <1522246943-2269-1-git-send-email-gerg@linux-m68k.org> (raw)
The iMX6ULL UART5_RX_DATA_SELECT_INPUT DAISY Register has some different
bit definitions to that same register in the iMX6UL.
The bits for the iMX6UL:
000 CSI_DATA00_ALT8 ? Selecting Pad: CSI_DATA00 for Mode: ALT8
001 CSI_DATA01_ALT8 ? Selecting Pad: CSI_DATA01 for Mode: ALT8
010 GPIO1_IO04_ALT8 ? Selecting Pad: GPIO1_IO04 for Mode: ALT8
011 GPIO1_IO05_ALT8 ? Selecting Pad: GPIO1_IO05 for Mode: ALT
100 UART5_TX_DATA_ALT0 ? Selecting Pad: UART5_TX_DATA for Mode: ALT
101 UART5_RX_DATA_ALT0 ? Selecting Pad: UART5_RX_DATA for Mode: ALT
But for the iMX6ULL:
000 CSI_DATA00_ALT8 ? Selecting Pad: CSI_DATA00 for Mode: ALT8
001 CSI_DATA01_ALT8 ? Selecting Pad: CSI_DATA01 for Mode: ALT8
010 GPIO1_IO04_ALT8 ? Selecting Pad: GPIO1_IO04 for Mode: ALT8
011 GPIO1_IO05_ALT8 ? Selecting Pad: GPIO1_IO05 for Mode: ALT
100 UART1_TX_DATA_ALT9 ? Selecting Pad: UART1_TX_DATA for Mode: ALT9
101 UART1_RX_DATA_ALT9 ? Selecting Pad: UART1_RX_DATA for Mode: ALT9
110 UART5_TX_DATA_ALT0 ? Selecting Pad: UART5_TX_DATA for Mode: ALT0
111 UART5_RX_DATA_ALT0 ? Selecting Pad: UART5_RX_DATA for Mode: ALT0
Specifically for a board I am working on with the serial console on UART5
I need to be able to enable UART5_RX_DATA_ALT0 mode. There is no definition
for the iMX6ULL version of that in imx6ul-pinfunc.h or imx6ull-pinfunc.h.
Add definitions for the missing UART5 input select register bits of the
iMX6ULL.
