arch/arm/src/stm32/hardware/stm32_dmamux.h,
arch/arm/src/stm32/hardware/stm32g47xxx_dmamux.h:
* New files, based on STM32G474RE reference manual, RM0440 Rev 4.
Used reference manual for STM32G071CB. The F0 and L0 families do not
appear to have a DMAMUX.
arch/arm/src/stm32f0l0g0/hardware/stm32_dmamux.h:
* Remove all mentions of DMAMUX12 from comments. This family has
at most DMAMUX1 only.
* Add missing defines DMAMUX_CCR_SPOL_NONE,
DMAMUX_CCR_SPOL_RISING, DMAMUX_CCR_SPOL_FALLING, and
DMAMUX_CCR_SPOL_BOTH.
* DMAMUX_CCR_SYNCID_SHIFT: Fix comment. Was "Bits 24-26" (3 bits)
but datasheet shows bits 24-28 (5 bits).
* DMAMUX_CCR_SYNCID_MASK: Fix mask. Was 0x7 (3 bits) but datasheet
shows (5 bits) 0x1f.
* DMAMUX1_CSR_SOF(x): Add parenthesis around macro parameter
expansion.
* DMAMUX1_CFR_SOF(x): Rename to DMAMUX1_CFR_CSOF(x) for
consistency with datasheet and add parenthesis around macro
parameter expansion.
* DMAMUX_RGCR_GPOL_MASK: Fix incorrect mask. Was 0x7 (3 bits) but
datasheet shows only 2 bits (0x3).
* Add missing defines DMAMUX_RGCR_GPOL_NONE,
DMAMUX_RGCR_GPOL_RISING, DMAMUX_RGCR_GPOL_FALLING, and
DMAMUX_RGCR_GPOL_BOTH.
* DMAMUX_RGCR_GNBREQ_SHIFT: Fix incorrect value. Was 17 (collision
with DMAMUX_RGCR_GPOL_SHIFT) but datasheet and comment both show
this bitfield at bits 19-23.
* DMAMUX_RGCR_GNBREQL_MASK: Fix incorrect mask. Was 0x7 (3 bits)
but datasheet shows 5 bits (0x1f).
* DMAMUX1_RGSR_SOF(x): Rename to DMAMUX1_RGSR_OF(x) for
consistency with datasheet and add parenthesis around macro
parameter expansion.
* DMAMUX1_RGCFR_SOF(x): Rename to DMAMUX1_RGCFR_COF(x) for
consistency with datasheet and add parenthesis around macro
parameter expansion.
* DMAMAP_MAP(d,c): Add parenthesis around macro parameter
expansion.
* Fix nxstyle errors.
arch/arm/src/stm32/hardware/stm32_spi.h:
* Avoid numerous ifdef on STM32 part numbers and make the
different variations of SPI peripheral features more
self-documenting: based on STM32_HAVE_IP_SPI_V* defines
from chip.h, define some or all of HAVE_SPI_I2S,
HAVE_SPI_TI_MODE, HAVE_SPI_ARB_DATA_SIZE, HAVE_SPI_FIFOS,
HAVE_SPI_NSSP, HAVE_SPI_I2S_ASTRT, and make decisions on
which registers and bitfields to define based on them.
* Define registers and bitfields for STM32_HAVE_IP_SPI_V4,
currently used only for STM32G47XX family MCUs, including
SPI_CR1_CRCL, SPI_CR2_NSSP, SPI_CR2_FRXTH, SPI_CR2_LDMARX,
SPI_CR2_LDMATX, SPI_CR2_DS_SHIFT/SPI_CR2_DS_MASK,
SPI_SR_FRLVL_SHIFT/SPI_SR_FRLVL_MASK, and
SPI_I2SCFGR_ASTRTEN.
* SPI_I2SCFGR_I2SSTD_PHILLIPS: Was defined incorrectly as
(xx << SPI_I2SCFGR_I2SSTD_SHIFT). Corrected this to
(0 << SPI_I2SCFGR_I2SSTD_SHIFT).
* SPI_I2SCFGR_I2SSTD_MSB: Was defined incorrectly as
(0 << SPI_I2SCFGR_I2SSTD_SHIFT). Corrected this to
(1 << SPI_I2SCFGR_I2SSTD_SHIFT).
* Fix nxstyle errors.
arch/arm/include/stm32/chip.h:
* Add new section "Peripheral IP versions" and specify version of
SPI IP block for STM32F10XX, STM32F20XX, STM32F30XX, STM32F33XX,
STM32F37XX, STM32F4XXX, STM32G47XX, and STM32L15XX.
arch/arm/src/stm32h7/hardware/stm32_dmamux.h:
* DMAMUX1_CSR_SOF(x): Add parenthesis around macro parameter
expansion.
* DMAMUX1_CFR_SOF(x): Rename to DMAMUX1_CFR_CSOF(x) for
consistency with datasheet and add parenthesis around macro
parameter expansion.
* DMAMUX_RGCR_GPOL_MASK: Fix incorrect mask. Was 7 (3 bits) but
datasheet shows only 2 bits.
* Add missing defines DMAMUX_RGCR_GPOL_NONE,
DMAMUX_RGCR_GPOL_RISING, DMAMUX_RGCR_GPOL_FALLING, and
DMAMUX_RGCR_GPOL_BOTH.
* DMAMUX_RGCR_GNBREQ_SHIFT: Fix incorrect value. Was 17 (collision
with DMAMUX_RGCR_GPOL_SHIFT) but datasheet and comment both show
this bitfield at bits 19-23.
* DMAMUX_RGCR_GNBREQL_MASK: Fix incorrect mask. Was 7 (3 bits) but
datasheet shows 5 bits.
* DMAMUX1_RGSR_SOF(x): Rename to DMAMUX1_RGSR_OF(x) for
consistency with datasheet and add parenthesis around macro
parameter expansion.
* DMAMUX1_RGCFR_SOF(x): Rename to DMAMUX1_RGCFR_COF(x) for
consistency with datasheet and add parenthesis around macro
parameter expansion.
* DMAMAP_MAP(d,c): Add parenthesis around macro parameter
expansion.
