2024-11-03soc: qcom: llcc: add support for SAR2130P and SAR1130PDmitry Baryshkov2-6/+466
Implement necessary support for the LLCC control on the SAR1130P and SAR2130P platforms. These two platforms use different ATTR1_MAX_CAP shift and also require manual override for num_banks.

2024-09-28Reduce Coccinelle choices in string_choices.cocciJulia Lawall1-50/+41
The isomorphism neg_if_exp negates the test of a ?: conditional, making it unnecessary to have an explicit case for a negated test with the branches inverted. At the same time, we can disable neg_if_exp in cases where a different API function may be more suitable for a negated test. Finally, in the non-patch cases, E matches an expression with parentheses around it, so there is no need to mention () explicitly in the pattern. The () are still needed in the patch cases, because we want to drop them, if they are present. Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>
