Dear Peter Tyser, In message [EMAIL PROTECTED] you wrote: I'm not sure if we need such a detailed level of access to these chips. We already have a couple of similar I/O expanders in some boards, for example implemente in some PICs. See for example the pic read / pic write

[U-Boot] [PATCH 1/3] Add support for PCA953x I2C gpio devices

2008-10-23 Thread Peter Tyser
Initial support for NXP's 4 and 8 bit I2C gpio expanders (eg pca9537, pca9557, etc). The CONFIG_PCA953X define enables support for the devices while the CONFIG_CMD_PCA953X define enables the pca953x command. Signed-off-by: Peter Tyser [EMAIL PROTECTED] --- Makefile |2 + README
