spi/imx: add support for imx51's eCSPI and CSPI · 0b599603

由 Uwe Kleine-König 提交于 9月 09, 2010

i.MX51 comes with two eCSPI interfaces (that are quite different from
what was known before---the tried and tested Freescale way) and a CSPI
interface that is identical to the devices found on i.MX25 and i.MX35.

This patch is a merge of two very similar patches (by Jason Wang and Sascha
Hauer resp.) plus a (now hopefully correct) reimplementation of the
clock calculation.

spi/imx: convert driver to use platform ids · f4ba6315

由 Uwe Kleine-König 提交于 9月 09, 2010

This has the advantage not to need to much cpu_is_... macros.  Still more
when imx51 support is added which has two different spi interfaces which
would introduce additional checks on the device id.

With this setup it's not possible for the compiler anymore to detect the
unused functions, so four additional kconfig symbols are introduced to
ifdef out the unneeded functions in the callback array and all these
functions are marked with __maybe_unused to suppress the corresponding
gcc warnings.

Comparing the driver footprint with and without the patch for a mx27
kernel yields:

add/remove: 2/0 grow/shrink: 2/0 up/down: 280/0 (280)
function                                     old     new   delta
spi_imx_devtype                                -     192    +192
spi_imx_probe                                980    1032     +52
spi_imx_devtype_data                           -      32     +32
spi_imx_setupxfer                            276     280      +4

Later when the platform code is updated to use the platform ids, the
autodetection can be removed which will make the driver a bit smaller
again.  (~60 Bytes in my test.)

Group soc specific data in a global struct instead of repeating it for
each call to imxXX_add_spi_imxX. The structs holding the actual data
are placed in .init.constdata and so don't do much harm. Compared to
the previous approach this reduces code size to call imx_add_spi_imx.
