read_zsreg

Name

read_zsreg --  Read a register from a Z85230

Synopsis

u8 read_zsreg (struct z8530_channel * c, u8 reg);

Arguments

c

Z8530 channel to read from (2 per chip)

reg

Use a spinlock.

Most of the Z8530 registers are indexed off the control registers. A read is done by writing to the control register and reading the register back. We do the locking needed to protect this operation.
