mmc: dw_mmc: Add support for 64-bit IDMAC ...
Some DW MMC blocks (e.g. those on modern Exynos chips) support 64-bit
DMA addressing mode. 64-bit DW MMC variants differ from their 32-bit
counterparts:
- the register layout is a bit different (because there are additional
IDMAC registers present for storing upper part of 64-bit addresses)
- DMA descriptor structure is bigger and different from 32-bit one
Introduce all necessary changes to enable support for 64-bit DMA capable
DW MMC blocks. Next changes were made:
1. Check which DMA address mode is supported in current IP-core
version. HCON register (bit 27) indicates whether it's 32-bit or
64-bit addressing. Add boolean .dma_64bit_address field to struct
dwmci_host and store the result there. dwmci_init_dma() function is
introduced for doing so, which is called on driver's init.
2. Add 64-bit DMA descriptor (struct dwmci_idmac64) and use it in
dwmci_prepare_desc() in case if .dma_64bit_address field is true.
A new dwmci_set_idma_desc64() function was added for populating that
descriptor.
3. Add registers for 64-bit DMA capable blocks. To make the access to
IDMAC registers universal between 32-bit / 64-bit cases, a new
struct dwmci_idmac_regs (and corresponding host->regs field) was
introduced, which abstracts the hardware by being set to
appropriate offset constants on init. All direct calls to IDMAC
registers were correspondingly replaced by accessing host->regs.
4. Allocate and use 64-bit DMA descriptors buffer in case when IDMAC
is 64-bit capable. Extract all the code (except for the IDMAC
descriptors buffer allocation) from dwmci_send_cmd() to
dwmci_send_cmd_common(), so that it's possible to keep IDMAC
buffer (either 32-bit or 64-bit) on stack during send_cmd routine.
The insights for this implementation were taken from Linux kernel DW MMC
driver.
