Guys:
A platform I have inherited utilizes a GPIO on an I2C expander chip (MAX7314) as a SPI slave-select. I'm using the actual MPC52xx SPI peripheral, not a PSC. It looks like the current version of the MPC52xx SPI driver won't work with sleep-capable GPIOs for slave-selects. In particular, it looks like mpc52xx_spi_fsmstate_transfer() is an interrupt handler that calls mpc52xx_spi_chipsel(), which itself calls gpio_set_value(). Or, at least my kernel thinks so, since I get a barrage of oops-type output screaming at me whenever I hit the SPI device. :) Am I missing something, or is this a known (or at least now-identified) limitation of the current mpc52xx_spi.c?
