I am not aware of any special IPA behavior or handling that would be based on a specific SoC (as opposed to a specific version of the IPA it contains). Update a few other references to the code that talk about the SDM845 rather than just IPA v3.5.1. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>

net: ipa: relax 64-bit build requirement 2021-03-18T23:20:35+00:00 Alex Elder elder@linaro.org 2021-03-18T18:59:30+00:00 99e75a37bd0af8eb8a0560f48091672b1b6d9218 We currently assume the IPA driver is built only for a 64 bit kernel. When this constraint was put in place it eliminated some do_div() calls, replacing them with the "/" and "%" operators. We now only use these operations on u32 and size_t objects. In a 32-bit kernel build, size_t will be 32 bits wide, so there remains no reason to use do_div() for divide and modulo. A few recent commits also fix some code that assumes that DMA addresses are 64 bits wide. With that, we can get rid of the 64-bit build requirement.

net: ipa: add config dependency on QCOM_SMEM 2021-01-13T04:11:38+00:00 Alex Elder elder@linaro.org 2021-01-12T19:21:34+00:00 46e05e1df628ab054486eafcc06a3c6512b338a1 The IPA driver depends on some SMEM functionality (qcom_smem_init(), qcom_smem_alloc(), and qcom_smem_virt_to_phys()), but this is not reflected in the configuration dependencies. Add a dependency on QCOM_SMEM to avoid attempts to build the IPA driver without SMEM. This avoids a link error for certain configurations.

remoteproc: clean up notification config 2020-03-17T00:31:51+00:00 Alex Elder elder@linaro.org 2020-03-16T22:51:21+00:00 5e0ef51b161c79e1c768d240b38837bdc06e0506 Rearrange the config files for remoteproc and IPA to fix their interdependencies.
