Subject: [PATCH 0/5] nvmem: support more NVMEM cells variants
Date: Thu, 23 Dec 2021 12:07:50 +0100 [thread overview]
Message-ID: <20211223110755.22722-1-zajec5@gmail.com> (raw)
From: Rafał Miłecki <rafal@milecki.pl>
Some NVMEM devices don't have NVMEM cells at hardcoded offsets and they
can't be strictly specified in a binding. Those devices usually store
NVMEM cells in some internal format. We still need a way of referencing
such hidden / dynamic NVMEM cells.
This patchset adds support for bindings like:
nvram@1eff0000 {
compatible = "brcm,nvram";
reg = <0x1eff0000 0x10000>;
mac_addr: cell-0 {
label = "et0macaddr";
};
};
ethernet@18024000 {
compatible = "brcm,amac";
reg = <0x18024000 0x800>;
nvmem-cells = <&mac_addr>;
nvmem-cell-names = "mac-address";
};
Rafał Miłecki (5):
dt-bindings: nvmem: add "label" property to allow more flexible cells
names
nvmem: core: read OF defined NVMEM cell name from "label" property
dt-bindings: nvmem: allow referencing device defined cells by names
dt-bindings: nvmem: brcm,nvram: add NVMEM cell to example
nvmem: core: add cell name based matching of DT cell nodes
