Subject: [PATCH v5 0/6] add STM32 FMC2 EBI controller driver
Date: Fri, 12 Jun 2020 17:22:36 +0200 [thread overview]
Message-ID: <1591975362-22009-1-git-send-email-christophe.kerello@st.com> (raw)
The FMC2 functional block makes the interface with: synchronous and
asynchronous static devices (such as PSNOR, PSRAM or other memory-mapped
peripherals) and NAND flash memories.
Its main purposes are:
- to translate AXI transactions into the appropriate external device
protocol
- to meet the access time requirements of the external devices
All external devices share the addresses, data and control signals with the
controller. Each external device is accessed by means of a unique Chip
Select. The FMC2 performs only one access at a time to an external device.
Changes in v5:
- NAND:
- do not display errors if the driver is deferred.
- look at the parent compatible string to match what we expect.
- bindings:
- add Rob reviewed-by tag on patch 3.
- fix indent descriptions.
- add new NFC compatible string to handle reg number of entries.
Changes in v4:
- bindings:
- fix filename: st,stm32-fmc2-ebi.yaml
Changes in v3:
- NAND:
- rename labels used on errors
- add in the commit log the reason to increase FMC2_TIMEOUT_MS (patch 3)
- add Miquel reviewed-by tag (patches 2/4/5/9)
- EBI:
- move in memory folder
- merge MFD and BUS drivers to avoid a MFD driver
- bindings:
- pattern name has been modified
- vendor properties have been modified
- s/_/-/
- add unit suffix (-ns) on timing properties
