The errata impacts OMAP 2420|2430|3430, enable the workaround for these based on I2C IP block revision number instead of OMAP CPU type Signed-off-by: Moiz Sonasath Signed-off-by: Vikram Pandita Signed-off-by: Ben Dooks --- drivers/i2c/busses/i2c-omap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/i2c/busses/i2c-omap.c b/drivers/i2c/busses/i2c-omap.c index 16b39f470a7c..827da0858136 100644 --- a/drivers/i2c/busses/i2c-omap.c +++ b/drivers/i2c/busses/i2c-omap.c @@ -784,7 +784,7 @@ omap_i2c_isr(int this_irq, void *dev_id) * memory to the I2C interface. */ - if (cpu_is_omap34xx()) { + if (dev->rev <= OMAP_I2C_REV_ON_3430) { while (!(stat & OMAP_I2C_STAT_XUDF)) { if (stat & (OMAP_I2C_STAT_NACK | OMAP_I2C_STAT_AL)) { omap_i2c_ack_stat(dev, stat & (OMAP_I2C_STAT_XRDY | OMAP_I2C_STAT_XDR)); -- GitLab
