When CONFIG_HAS_IOMEM is not set/enabled, certain iomap() family
functions [including ioremap(), devm_ioremap(), etc.] are not
available.
Drivers that use these functions should depend on HAS_IOMEM so that
they do not cause build errors.
Rectifies these build errors:
s390-linux-ld: drivers/dma/qcom/hidma_mgmt.o: in function `hidma_mgmt_probe':
hidma_mgmt.c:(.text+0x780): undefined reference to `devm_ioremap_resource'
s390-linux-ld: drivers/dma/qcom/hidma_mgmt.o: in function `hidma_mgmt_init':
hidma_mgmt.c:(.init.text+0x126): undefined reference to `of_address_to_resource'
s390-linux-ld: hidma_mgmt.c:(.init.text+0x16e): undefined reference to `of_address_to_resource'

Enable support for the Qualcomm Technologies HIDMA Management.

Each DMA device requires one management interface driver
|
|
for basic initialization before QCOM_HIDMA channel driver can
|
|
start managing the channels. In a virtualized environment,
|
|
the guest OS would run QCOM_HIDMA channel driver and the
|

host would run the QCOM_HIDMA_MGMT management driver.

Enable support for the Qualcomm Technologies HIDMA controller.
|

The HIDMA controller supports optimized buffer copies
|
|
(user to kernel, kernel to kernel, etc.). It only supports
|
|
memcpy interface. The core is not intended for general
|
|
purpose slave DMA.
