A lot of patches are outdated versions of upstreamed patches and drivers. So lets pull in the upstreamed patches and reorder remaining ones. This drops the unnecessary 721-dts-ipq4019-add-ethernet-essedma-node.patch which adds nodes for not yet in OpenWrt IPQESS driver.

2020 12:30:01 +0100 Subject: [PATCH] regulator: add IPQ4019 SDHCI VQMMC LDO
|
|
driver
|
|
|
|
This introduces the IPQ4019 VQMMC LDO driver needed for
|
|
the SD/EMMC driver I/O level operation.
|
|
This will enable introducing SD/EMMC support for the built-in controller.
