[PATCH] i2c: let the core register devices from devicetree
From: Wolfram Sang <hidden>
Date: 2012-06-13 21:12:10
Currently, every driver has to do it on its own, but it should be done in the core, like we already do with board_info structs. Signed-off-by: Wolfram Sang <redacted> --- Based on v3.5-rc2. Only build tested, I don't have a OF based device around at the moment. @Peter: Why does ocores do the device registration manually via platform_data instead of using board_info? drivers/i2c/busses/i2c-cpm.c | 5 ----- drivers/i2c/busses/i2c-designware-platdrv.c | 1 - drivers/i2c/busses/i2c-gpio.c | 2 -- drivers/i2c/busses/i2c-ibm_iic.c | 3 --- drivers/i2c/busses/i2c-imx.c | 2 -- drivers/i2c/busses/i2c-mpc.c | 1 - drivers/i2c/busses/i2c-mxs.c | 2 -- drivers/i2c/busses/i2c-ocores.c | 2 -- drivers/i2c/busses/i2c-omap.c | 2 -- drivers/i2c/busses/i2c-pnx.c | 2 -- drivers/i2c/busses/i2c-pxa.c | 1 - drivers/i2c/busses/i2c-s3c2410.c | 1 - drivers/i2c/busses/i2c-sh_mobile.c | 1 - drivers/i2c/busses/i2c-tegra.c | 2 -- drivers/i2c/busses/i2c-versatile.c | 1 - drivers/i2c/busses/i2c-xiic.c | 2 -- drivers/i2c/i2c-core.c | 3 +++ 17 files changed, 3 insertions(+), 30 deletions(-)
