Subject[PATCH v2 1/2] net: ipa: fix v3.5.1 resource limit max values
Date
Some resource limits on IPA v3.5.1 have their max values set to
255, this causes a few splats in ipa_reg_encode and prevents the
IPA from booting properly. The limits are all 6 bits wide so
adjust the max values to 63.

Fixes: 1c418c4a929c ("net: ipa: define resource group/type IPA register fields")
Signed-off-by: Caleb Connolly <caleb.connolly@linaro.org>

V1: https://lore.kernel.org/netdev/20221024165636.3979249-1-caleb.connolly@linaro.org/
Changes since v1:
* Apply the correct fix for v3.1 which has the opposite issue where the masks
are wrong rather than the values.
* Split into two patches
